Samsung Galaxy S4: Touch Free Interaction Features

Another set of innovation that Samsung introduces in the Galaxy S4 is the ability to interact without touching the phone. To list a few:

- Air View: information appears when you hover your finger over the screen.
- Air Gesture: Quick glance, Air jump, Air browse, Air move, Air call-accept.
- Motion: Direct Call, Smart alert, Tilt Zoom, Pan, Turn over mute
- Smart screen: Smart stay, Smart rotation, Smart pause, Smart scroll

Some of the functions are rather useful, but here's the issue: not all works on apps.

Fortunately, you can easily enable and disable the gesture features via the dropdown menu.

My verdict: the touch free features are not deal-breakers, but they might help you interact with the phone when you don't want to touch your phone with your soiled hands.
